Plant Theory Organic Multi-Purpose Fertiliser Concentrate
Give your plants the organic treatment
Plant Theory multi-purpose fertiliser is a careful blend of seaweed and plant extracts, perfectly balanced to provide essential minerals and nutrients to vegetables, flowers, fruits, salad crops and even house plants. We've created it as a concentrate to minimise the packaging required, so one little sachet is all you need to make up a whole litre of plant-improving solution.
Seaweed contains natural plant nutrients such as Nitrogen and Potassium to improve plant immunity, enrich soil and provide strong and healthy growth
